The X-ray single-crystal structure of trilithium antimony tetraoxide, Li(3)SbO(4), is compared with the Rietveld refinement previously reported for the same material and shows that, as expected, powder data yield a less accurate structure. Department of Chemistry, University of Marburg, Marburg, Germany, You can also search for this author in This irreversibly dissolves the starch granule in water. A beam of X-rays strikes the crystal and the diffraction pattern is then used to study the structure, Matter can broadly be classified into two categories based on its internal structureamorphous and crystalline. To solve a crystal structure means to determine the precise spatial arrangements of all of the atoms in a chemical compound in the crystalline state. On the other hand, the ability of scattering X-rays is proportional to the atomic number (number of electrons), and thus X-ray diffraction is more suited to the structure determination of various materials from inorganic to organic compounds including proteins.
